Abstract

The invention discloses an anaerobic adhesive. The anaerobic adhesive is prepared from the following components in parts by weight: 13-28 parts of hydroxyl-terminated polybutadiene, 32-42 parts of toluene-2,4-diisocyanate, 40-50 parts of 2,4-toluene dicarbamate, 52-67 parts of poly(3,4-ethylenedioxythiophene) emulsion, 35-45 parts of toluene-2,4-diisocyanate, 20-35 parts of 2-hydroxy-2-methyl-1-phenyl-1-propanon and 10-26 parts of polyisoprene-b-polystyrene. The anaerobic adhesive has outstanding corrosion resistance, can prevent leakage and can be fastened with a sealed thread to prevent loosening and leakage due to vibration, impact, high temperature, medium corrosion and other factors, and double nuts, spring washers or other fasteners can be omitted.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an anaerobic adhesive. Background technique [0002] The concept of adhesive: Adhesive is a substance that firmly bonds various solid materials together by interfacial action (chemical force or physical force). It is also called adhesive or adhesive, referred to as "glue". [0003] Adhesives are widely used in various fields of the national economy, such as construction, packaging, aerospace, aviation, electronics, automobiles, machinery and equipment, medical and health care, and textiles. [0004] However, the corrosion resistance of the currently used anaerobic adhesives is not good, and the locking is not tight enough to meet the demand. Contents of the invention [0005] The technical problem mainly solved by the present invention is to provide an anaerobic adhesive, which has excellent corrosion resistance, can ensure no omissions, can lock and seal the screw thread due to facto...
